These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems.

[0040] In some wireless communications systems, a UE may measure channel state information (CSI) reference signals (CSI-RSs) transmitted by a network entity in order to perform channel estimation. For example, a network entity may output CSI-RSs within a CSI-RS resource across one or more ports (e.g., antenna ports, logical ports) , which the UE may receive, measure, and report back to the network entity. In some implementations, the network entity may support a threshold quantity of antenna ports (e.g., 32) for a CSI-RS resource to cover. However, a network entity may support greater than the threshold quantity of ports through port aggregation, such as by combining CSI-RS resources across multiple sets of ports into an aggregated CSI-RS resource, defined by a configuration and various sub-configurations. For example, in order to support more than a given threshold quantity of ports, a configuration for multiple resources may be broken into multiple sub-configurations, each of which may apply to, at most, the threshold quantity of ports. That is, the network entity may indicate sub-configurations that may apply to a subset of ports, the subset of ports less than or equal to the threshold quantity of ports, which can be aggregated into the full configuration and effectively support more than the threshold quantity of ports. In some implementations, the sub-configurations may be used to support network energy savings (NES) . That is, specific ports of the full set of ports may be active (e.g., other ports may be inactive for NES) . The specific ports may be mapped to a sub-configuration, which may be of smaller dimensions than the full set of ports. However, there may not be a way to index the ports of the sub-configurations such that measurement reports may be made for the sub-configuration of activated ports across multiple resources.
[0041] The techniques described herein may support port indexing methods to index port sub-configurations for NES. In some implementations, a sub-configuration may be configured to use the same indexing, or mapping, method as the full configuration. For example, the configuration and sub-configurations may map each polarization of a resource to a set of consecutive indices (e.g., method 1) based on a first dimension, or may map each polarization of a resource to multiple sets of consecutive indices (e.g., method 2) based on a second dimension. In other implementations, the configuration may be ordered using method 1 or method 2. However, the sub-configuration may be ordered such that each resource contains a consecutive set of indices for each polarization. In some cases, a series of available ports in an NES sub-configuration may have dimensions that may not be supported. For example, a first dimension may be less than a second dimension. The UE may swap the dimensions, such that the first dimension is greater than the second dimension to support the indexing.
[0042] Aspects of the disclosure are initially described in the context of wireless communications systems, port-to-resource mappings, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to port indexing for NES.
[0043] FIG. 1 shows an example of a wireless communications system 100 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0044] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0045] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0046] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0047] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0048] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0049] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0050] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0051] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0052] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support port indexing for NES as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0053] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0054] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0055] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0056] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0057] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0058] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0059] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0060] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0061] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0062] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0063] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) ) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0064] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0065] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0066] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0067] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0068] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0069] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0070] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0071] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0072] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0073] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0074] In some wireless communications systems 100, a UE 115 may measure channel state information (CSI) reference signals transmitted by a network entity 105 in order to perform channel estimation. For example, a network entity 105 may output CSI-RSs within a CSI-RS resource across one or more ports (e.g., antenna ports, logical ports) , which the UE 115 may receive, measure, and report back to the network entity 105. In some implementations, the network entity 105 may support a threshold quantity of antenna ports (e.g., 32) for a CSI-RS resource to cover. However, a network entity 105 may support greater than the threshold quantity of ports through port aggregation, such as by combining CSI-RS resources across multiple sets of ports into an aggregated CSI-RS resource, defined by a configuration and various sub-configurations. For example, in order to support more than a given threshold quantity of ports, a configuration for multiple resources may be broken into multiple sub-configurations, each of which may apply to, at most, the threshold quantity of ports. That is, the network entity 105 may indicate sub-configurations that may apply to a subset of ports, the subset of ports less than or equal to the threshold quantity of ports, which can be aggregated into the full configuration and effectively support more than the threshold quantity of ports. In some implementations, the sub-configurations may be used to support NES. That is, specific ports of the full set of ports may be active (e.g., other ports may be inactive for NES) . The specific ports may be mapped to a sub-configuration, which may be of smaller dimensions than the full set of ports.
[0075] Some wireless communications systems 100 may port indexing methods to index port sub-configurations for NES. That is, the network entity 105 may configure the UE 115 to index the ports of the sub-configurations such that measurement reports may be made for the sub-configuration of activated ports across multiple resources. In some implementations, ports indicated within a sub-configuration may be configured to use the same indexing, or mapping, method as the full configuration. For example, the configuration and sub-configurations may map each polarization of a resource to a set of consecutive indices (e.g., method 1) based on a first dimension, or may map each polarization of a resource to multiple sets of consecutive indices (e.g., method 2) based on a second dimension. In other implementations, the full configuration may be ordered using method 1 or method 2. However, the sub-configuration may be ordered such that each resource contains a consecutive set of indices for each polarization. In some cases, a series of available ports in a sub-configuration may have dimensions that may not be supported. For example, a first dimension may be less than a second dimension. The UE 115 may swap the dimensions, such that the first dimension is greater than the second dimension, to support the indexing.
[0076] FIG. 2 shows an example of a wireless communications system 200 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement, or be implemented by, aspects of the wireless communications system 100. For example, the wireless communications system 200 may include network entity 105-a and UE 115-a, which may be examples of corresponding devices as described herein, including with reference to FIG. 1. The techniques described herein in the context of the wireless communications system 200 may support methods for port indexing of a sub-configuration to map CSI-RS resources to ports in order to support NES.
[0077] In some implementations, a network entity 105-a may support channel estimation, via transmission of CSI-RSs, for multiple ports 210 (e.g., antenna ports) . For example, the network entity 105-a may have up to 128 ports 210. One CSI-RS resource may support up to thirty two ports 210. In order to support up to 128 ports 210 across multiple CSI-RS resources, the network entity 105-a may extend methods used for indexing ports 210 across one CSI-RS resource. In some cases, additional parameters may be defined defining a quantity of ports 210.
[0078] In some wireless communications systems 200, the network entity 105-a may transmit, via communication link 205, control signaling 215. Control signaling 215 may indicate a configuration (e.g., CSI-ReportConfig) for a UE 115-a to use to perform channel estimation measurements and report measurement results to the network entity 105-a. The UE 115-a may report measurement results via measurement report 220. The configuration may indicate parameters related to CSI-RS resources for performing channel measurements (e.g., resourcesForChannelMeasurement) , content of reports (e.g. rank indicator (RI) , channel quality indicator (CQI) , precoding matrix indicator (PMI) , CSI-RS resource indicator (CRI) , configured by parameter reportQuantity) , a codebook configuration (e.g., codebookConfig) , a port indexing mapping method for the UE 115-a to use to map CSI-RS resources to ports 210 at the network entity 105-a (e.g., portMappingMethod) , a list of sub-configurations (e.g., CSI-ReportSubConfigs) for the configuration (e.g., csi-ReportSubConfigToAddModList) , or the like.
[0079] In some implementations, a parameter related to CSI-RS resources for performing channel measurements (e.g., resourcesForChannelMeasurement) may indicate a CSI-RS resource configuration (e.g., CSI-ResourceConfig) . The CSI-RS resource configuration may include a parameter indicating a timing type of CSI-RS resource, such as aperiodic (AP) , semipersistent (SP) , or periodic (P) (e.g., resourceType {P, SP, AP} ) . Additionally, or alternatively, the CSI-RS resource configuration may include a parameter related to a list of CSI-RS resource sets or list of CSI-RS resources (e.g., csi-RS-ResourceSetList) . The CSI-RS resource set list may indicate configurations of sets of CSI-RS resources, which may be non-zero power (NZP) CSI-RS resources (e.g., NZP-CSI-RS-ResourceSet) . The configuration of the set of CSI-RS resources may include parameters indicating CSI-RS resources within the set (e.g., nzp-CSI-RS-Resources) , offsets related to triggering aperiodic resources (e.g., aperiodicTriggeringOffset) , or the like.
[0080] In some implementations, within the configuration, the list of sub-configurations may be indicated and configured. A sub-configuration (e.g., CSI-ReportSubConfig) may include a parameter related to indicating a subset of ports 210 at the network entity 105-a (e.g., portSubsetIndicator) , which may relate to the indication of CSI-RS resources within the CSI-RS resource set configuration for the full configuration (e.g., nzp-CSI-RS-Resources) . Additionally, or alternatively, the sub-configuration may include a parameter indicating a list of CSI-RS resources for the sub-configuration (e.g., nzp-CSI-RS-ResourceList) , which may be associated with the configuration of sets of CSI-RS resources for the full configuration (e.g., NZP-CSI-RS-ResourceSet) . Additionally, or alternatively, the sub-configuration may include a power offset for performing measurements (e.g., powerOffset) , an indication of a codebook configuration (e.g., codebookConfig) , which may include an indication of one or more dimension sizes (e.g., N1, N2) of the subset of ports 210 at the network entity 105-a, an indication of a port indexing mapping method for mapping CSI-RS resources to ports 210 at the network entity 105-a for the sub-configuration (e.g., portMappingMethod) , or the like. That is, the network entity 105-a may transmit, via control signaling 215, indications of configurations and sub-configurations for the UE 115-a to use to map CSI-RS resources to ports 210 at the network entity 105-a for performing channel state measurements.
[0081] In some implementations, to support NES, a network entity 105-a may adapt (e.g., enable, disable) spatial elements, such as logical ports or physical antennas, at the network entity 105-a, which may correspond to ports 210. In some cases, the UE 115-a may assist the network entity 105-a in determining the adaptation. In some examples, the sub-configurations may adapt a spatial-domain subset of resources or ports 210. For example, a configuration may indicate to use a subset of ports 210 by shutting down at least some transceiver units (TXRUs) (e.g., Type1 spatial element adaptation) . That is, all antenna elements (AEs) of one or more logical ports 210 at the network entity 105-a may be disabled or enabled. The subset of ports 210 may be indicated within the sub-configuration (e.g., portSubsetIndicator) , which may indicate a subset of ports 210 via a bitmap, where the subset of ports 210 may apply to all CSI-RS resources. Additionally, or alternatively, a configuration may indicate to use a subset of CSI-RS resources by shutting down at least some AEs of a logical port associated with ports 210 (e.g., Type2 spatial element adaptation) . That is, a subset of AEs associated with a logical antenna port of the ports 210 may be enabled or disabled. In some cases, disabling the subset of AEs of a logical port may correspond to adjusting a quantity of CSI-RS resources to a subset of CSI-RS resources associated with a full configuration. The subset of CSI-RS resources may be indicated within the sub-configuration (e.g., NZP-CSI-RS-ResourceSet) . In some implementations, the UE 115-a may transmit feedback or measurement information associated with multiple spatial element configurations within a single measurement report 220 (e.g., CSI report) .
[0082] In some wireless communication systems 200, configuring a sub-configuration may be combined with techniques for NES by providing a sub-configuration for measuring a subset of activated ports 210 at the network entity 105-a across multiple resources. To support NES, the network entity 105-a may disable some of the ports 210. The available, or enabled, ports 210 may be indicated with a sub-configuration of the configuration that includes the available ports 210 and the disabled ports 210. The sub-configuration may span multiple CSI-RS resources, as described herein. For example, an indication of a subset of ports 210 (e.g., port-subsetIndicator) may span a configuration of more than 32 ports 210 (e.g., p48, p64, p128) , extending an associated mapping (e.g., bitmap) for a sub-configuration. The UE 115-a may use a sub-configuration for port indexing in order to determine which of the subset of ports 210 (e.g., available ports 210) correspond to which of the multiple CSI-RS resources.
[0083] In some implementations, a quantity of ports 210 may be between 32 and 128. Some quantity of CSI-RS resources (K) (e.g., NZP CSI-RS resources) , which individually may support up to 32 CSI-RS resources, may be aggregated to support the quantity of ports 210. That is, the quantity of CSI-RS resources, K, may be aggregated into a virtual CSI-RS resource, extending a port bitmap from less than or equal to 32 bits to 48, 64, or 128 bits, depending on the configuration. A total quantity of ports 210, P, may be divided between the CSI-RS resources, K, resulting in a quantity of ports 210 per CSI-RS resource, Q. In some examples, specific combinations of quantity of ports 210, P, and quantities of CSI-RS resources, K, may be supported. For example, for 48 ports 210 (e.g., P=48) , the quantity of CSI-RS resources may be two (e.g., K=2) , where each resource covers 24 ports 210 (e.g., Q=24) or three (e.g., K=3) , where each CSI-RS resource covers 16 ports 210 (e.g., Q=16) . For 64 ports 210 (e.g., P=64) , the quantity of CSI-RS resources may be two (e.g., K=2) , where each CSI-RS resource covers 32 ports 210 (e.g., Q=32) or four (e.g., K=4) , where each CSI-RS resource covers 16 ports 210 (e.g., Q=16) . For 128 ports 210 (e.g., P=128) , the quantity of CSI-RS resources may be 4, where each CSI-RS resource covers 32 ports 210 (e.g., Q=32) .
[0084] In some implementations, to support channel estimation for wireless communications systems 200 that may support an aggregated CSI reference single resource comprising multiple CSI-RS resources that may map to a quantity of ports 210, the network entity 105-a may configure the UE 115-a with a port index ordering within a bitmap of a NES spatial element adaptation. The network entity 105-a may transmit, via control signaling 215, an indication of a port indexing method for mapping CSI-RS resources to available ports 210 at the network entity 105-a (e.g., portMappingMethod) . That is, the network entity 105-a may configure the UE 115 to index the ports 210 of the sub-configurations such that measurement reports may be made for the sub-configuration of activated ports 210 across multiple CSI-RS resources. In some implementations, the subset of ports 210 indicated within a sub-configuration may be configured to use the same indexing, or mapping, method as the configuration associated with the sub-configuration. For example, the configuration and sub-configurations may map each polarization of a CSI-RS resource to a set of consecutive indices (e.g., method 1) based on a first dimension, or may map each polarization of a CSI-RS resource to multiple sets of consecutive indices (e.g., method 2) based on a second dimension, as described further with reference to FIGs. 3A and 3B. In other implementations, the full configuration may be ordered using method 1 or method 2. However, the sub-configuration may be ordered such that each resource contains a consecutive set of indices across the resource, as described further with reference to FIGs. 3A and 3B. In some cases, a series of available ports 210 in a sub-configuration may have dimensions that may not be supported. For example, a first dimension may be less than a second dimension. The UE 115-a may swap the dimensions, such that the first dimension is greater than the second dimension, to support port indexing, as described further with reference to FIG. 5.
[0085] FIGs. 3A and 3B show examples of a port-to-resource mappings 300 and 301, respectively, that support port indexing for NES in accordance with one or more aspects of the present disclosure. The port-to-resource mappings 300 and 301 may implement, or be implemented by, aspects of the wireless communications systems 100 or 200. The techniques described herein in the context of the port-to-resource mappings 300 and 301 may support port indexing a CSI report configuration and sub-configuration in order to map CSI-RS resources to ports at a network entity to support CSI reports for multiple CSI-RS resources, and to support NES.
[0086] Further, port-to-resource mappings 300 and 301, respectively, support port indexing for CSI report with >32 CSI-RS ports and associated with “virtual” resource consisting of multiple CSI-RS resources. The CSI report with > 32port “virtual” resource consisting of multiple CSI-RS resources may be further configured with CSI-ReportSubConfigs for NES in accordance with one or more aspects of the present disclosure. Accordingly, the techniques described herein in the context of the port-to-resource mappings 300 and 301 may support port indexing a CSI report configuration or sub-configuration in order to map CSI-RS resources to ports at a network entity to support CSI report with > 32port “virtual” resource consisting of multiple CSI-RS resources, and to support NES.
[0087] In some implementations, to support channel estimation for a wireless communications systems that may support multiple CSI-RS resources, forming a virtual or aggregated CSI-RS resource (e.g., a virtual CSI-RS resource for more than 32 ports) , that may map to ports at the network entity, the network entity may transmit, via control signaling, an indication of a port indexing method for a sub-configuration of the configuration. The port indexing method may support mapping CSI-RS resources to a subset of ports at the network entity (e.g., portMappingMethod) , which may be available (e.g, enabled, activated) ports for NES. That is, the network entity may configure the UE to index ports of sub-configurations such that measurement reports may be made for sub-configurations of activated ports across multiple CSI-RS resources. The port indexing may be sequential or consecutive across a quantity of indices (e.g., Q) . That is, the port indexing may be a linearly increasing sequence {i0, i1, ..., iQ-1} such that iq < iq+1. In some cases, q = 0, 1, ..., Q -2 or q+1= 1, ..., Q-1, which may be a port index within a CSI-RS resource. iq or iq+1 ∈ {0, 1, ..., KQ-1} may be the port index for a codebook, as described with reference to FIG. 2, across multiple CSI-RS resources. To define the indices (e.g., iq) , the network entity may configure, via control signalling (e.g., higher-layer signalling, RRC signalling) the UE with a mapping method for mapping from a CSI-RS resource index or port index for a CSI-RS resource to support CSI and PMI calculations. In some cases, a codebook (e.g., Type-I and Type-II codebook) may support the signalling to configure the UE. The port-to-resource mappings 300 and 301 may provide examples of configurable mapping methods.
[0088] With respect to port-to-resource mapping 300, a sub-configuration for a subset of ports may indicate for the UE to use the same indexing, or mapping, method as the full configuration for port indexing of the sub-configuration. For example, bits in a bitmap of a sub-configuration may correspond to port indices following the order of a mapping method for the configuration. In some implementations, the configuration may indicate a mapping method based on a first dimension of the ports (e.g., N1-dimension aggregation, mapping method 1) . That is, port indexing may follow a sequential ordering or indexing through resources and polarization of ports. The ports may support two polarizations, a first polarization and a second polarization. The port indexing may be sequential within a first resource 310 and a first polarization, then sequential for a second resource 310 and first polarization, until the final resource 310 (e.g., K-th resource) for the first polarization. The sequential, or consecutive, indexing may continue for the first resource 310 and a second polarization, a second resource 310 and the second polarization, up to the final resource 310 and the second polarization (e.g., sequential ordering / indexing within (1st resource 310, 1st polarization) , then (2nd resource 310, 1st polarization) , …, then (Kth resource 310, 1st polarization) , then (1st resource 310, 2nd polarization) , then (2nd resource 310, 2nd polarization) , …, then (Kth resource 310, 2nd polarization) ) .
[0089] For example, a mapping 305 for a configuration that may support 64 ports may have a first dimension of eight (e.g., N1=8) and a second dimension of four (e.g., N2=4) , such that the total ports (P) may be double the first dimension multiplied by the second dimension (e.g., P = 2 N1 N2 = 64) . The configuration may also indicate two CSI-RS resources (e.g., K=2) . Thus, each CSI-RS resource may be mapped to 32 ports (e.g., P = KQ = 64, Q=32) . The ports may be indexed such that a first set of indices (e.g., 0–15) may correspond to a set of ports of a first polarization mapped to a resource 310-a. A second set of indices (e.g., 16–31) may correspond to a set of ports of the first polarization mapped to a resource 310-b. A second set of indices (e.g., 32–47) may correspond to a set of ports of a second polarization mapped to a resource 310-a. A second set of indices (e.g., 48–63) may correspond to a set of ports of the second polarization mapped to a resource 310-b.
[0090] A sub-configuration may indicate to use the same port indexing method as mapping 305. For example, the ports of a sub-configuration may be indexed consecutively across resources 310 based on a first dimension, in accordance with polarizations of the ports.
[0091] With respect to port-to-resource mapping 301, in some implementations, the configuration may indicate a mapping method based on a second dimension of the ports (e.g., N2-dimension aggregation) . That is, port indexing may follow a sequential ordering or indexing through polarization of ports and resources 320. The ports may support two polarizations, a first polarization and a second polarization. The port indexing may be sequential within a first polarization, but split between resources 320. That is, based on the second dimension and a quantity of resources 320, the port indexing may be sequential through resources in sets of small quantities of ports (e.g., n2, where K*n2 = N2) . That is, within a first polarization, the indexing may be sequential from the first n2 ports in a first resource, then the first n2 ports for a second resource, until the first n2 ports for the final resource 320 (e.g., Kth resource) , then may repeat the pattern through the final set of n2 ports in the final resource 320 (e.g., Kth resource) (e.g., N1 sets of n2 ports for each of the K resources) . The sequence may continue for the second polarization, following the indexing pattern through the resources 320 (e.g., sequential ordering / indexing within (where K*n2 = N2) . For the 1st polarization, (1st n2 ports in 1st resource 320, 1st polarization) , (1st n2 ports in 2nd resource 320, 1st polarization) , …, (1st n2 ports in Kth resource 320, 1st polarization) , then (2nd n2 ports in 1st resource 320, 1st polarization) , (2nd n2 ports in 2nd resource 320, 1st polarization) , …, (2nd n2 ports in Kth resource 320, 1st polarization) , …then (N1th n2 ports in 1st resource 320, 1st polarization) , (N1th n2 ports in 2nd resource 320, 1st polarization) , …, (N1th n2 ports in Kth resource 320, 1st polarization) , and then for the 2nd polarization, (1st n2 ports in 1st resource 320, 2nd polarization) , (1st n2 ports in 2nd resource 320, 2nd polarization) , …, (1st n2 ports in Kth resource 320, 2nd polarization) , then (2nd n2 ports in 1st resource 320, 2nd polarization) , (2nd n2 ports in 2nd resource 320, 2nd polarization) , …, (2nd n2 ports in Kth resource 320, 2nd polarization) , …then (N1th n2 ports in 1st resource 320, 2nd polarization) , (N1th n2 ports in 2nd resource 320, 2nd polarization) , …, (N1th n2 ports in Kth resource 320, 2nd polarization) ) .
[0092] For example, a mapping 315 for a configuration that may support 64 ports may have a first dimension of eight (e.g., N1=8) and a second dimension of four (e.g., N2=4) , such that the total ports (P) may be double the first dimension multiplied by the second dimension (e.g., P = 2 N1 N2 = 64) . The configuration may also indicate two CSI-RS resources (e.g., K=2) . Thus, each CSI-RS resource 320 may be mapped to 32 ports (e.g., P = KQ = 64, Q=32) . The set of ports within a resource 320 may be two (e.g., K *n2 = N2 = 4, n2 = 2) . The ports may be indexed such that eight alternating sets of consecutive indices (e.g., 0, 1, 4, 5, 8, 9, and so on) may correspond to a first resource 320-a within a first polarization. Eight sets of consecutive indices that may alternate with the indices related to the first resource 320-a (e.g., 2, 3, 6, 7, 10, 11, and so on) may correspond to a second resource 320-b within the first polarization. The same pattern may be followed for a second polarization, such that indices 32–63 are distributed across resource 320-a and 320-b in alternating sets of consecutive indices, each set of consecutive indices including two indices.
[0093] A sub-configuration may indicate to use the same port indexing method as mapping 315. For example, the ports of a sub-configuration may be indexed in sets of consecutive indices across a resource 320 and across polarizations.
[0094] In some implementations, a CSI report sub-configuration may not follow the ordering or port indexing method indicated in the associated CSI report configuration (e.g., mapping method 1, mapping method 2) . Instead, the sub-configuration may indicate for a port indexing method that may result in consecutive indexing across a resource 310 or 320. For example, a first resource 310 may be consecutively indexed across a first polarization and a second polarization of ports, then a second resource 310 may be consecutively indexed across the first polarization and the second polarization, and so on until the final resource 310 (e.g., K) . That is, all the Q ports for a resource 310 may be consecutively indexed (e.g., Q / 2 consecutive indices for a first polarization and Q / 2 consecutive indices for a second polarization for a resource 310) , then the next Q ports for a next resource 310 may be consecutively indexed.
[0095] FIG. 4 shows an example of a port-to-resource mapping 400 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The port-to-resource mapping 300 may implement, or be implemented by, aspects of the wireless communications systems 100 or 200 or port-to-resource mappings 300 or 301. The techniques described herein in the context of the port-to-resource mapping 400 may support methods support port indexing a sub-configuration indicated in a full configuration in order to map CSI-RS resources to a subset of ports to support NES.
[0096] In some implementations, a network entity may support NES procedures. A network entity may enable available ports 405 and disable other ports 410 for channel estimation. By enabling a subset of ports, available ports 405, the network entity may save energy that may have been used for other ports 410, among other benefits. Within a mapping 415 associated with a configuration, available ports 405 and other ports 410 may be mapped. A sub-configuration may indicate a mapping 425, which may map the available ports 405. For example, the sub-configuration may include a port bitmap indicating available ports 405, such as with a bit value of one. The available ports 405 may be mapped to consecutive antenna ports. and across respective resource 420, such as resources 420-a and 420-b as indicated by the configuration. For example, the antenna ports corresponding to the available ports 405 indicated by the bitmap may be mapped to consecutive antenna ports, starting with a first antenna port (e.g., CSI-RS antenna port 3000) in increasing order based on a respective bit position in the bitmap. The indicated available ports 405 may be based on some precoder, which may be given by Equation 1 (e.g., the UE may determine indices (e.g., channel quality index (CQI) , resource index (RI) , precoding matrix index (PMI) ) based on the precoder) .
[0097] y may refer to signals at indicated antenna ports. x may be a vector of PDSCH symbols for a layer mapping. v may correspond to a quantity of layers in a set. P may correspond to the available ports (e.g., CSI-RS ports) , or the quantity of bits with a value of one in the bitmap. W (i) may be a precoding matrix. For a given type of precoding matrix index (PMI) (e.g., Type-I PMI, rank-1) , which may be defined based on the dimensions of a sub-configuration using Equations 2 and 3. may be a phase applied to the vector, such that vl, m may refer to a first polarization and may refer to a second polarization.
[0098] N1 and N2 may be the dimensions of the mapping 415 or 425. j may be a j-th CSI-RS resource. O1 and O2 may be configured values corresponding to N1 and N2, which may be configured or indicated via a table or the like. m and l. may be the elements of vector vl, m and may be configured or defined based on a table, a configuration from the network entity, or the like.
[0099] [Rectified under Rule 91, 19.12.2024]In some implementations, as described with reference to FIGs. 3A and 3B, a sub-configuration may indexed on a resource-by-resource basis (e.g., a consecutive set of indices across an entire resource, for both polarizations) . In some cases, antenna ports corresponding to the available ports at the network entity may be permuted to the physical antenna ports using the precoder in Equation 1. In order to support Equation 1, the available ports 405 may be indexed according to a different ordering method (e.g., mapping method 1, mapping method 2) that may be the same as a port indexing of a full CSI report configuration associated with the CSI report sub-configuration. That is, available ports 405 of a sub-configuration may be permuted according to a port indexing method of a configuration and may be mapped to consecutive antenna ports, starting at CSI-RS antenna port 3000, based on the precoding definition, even for a sub-configuration that may use a different port indexing procedure than an associated configuration.
[0100] FIG. 5 shows an example of a port-to-resource mapping 500 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The port-to-resource mapping 300 may implement, or be implemented by, aspects of the wireless communications systems 100 or 200 or port-to-resource mappings 300, 301, or 400. The techniques described herein in the context of the port-to-resource mapping 500 may support port indexing a sub-configuration to map CSI-RS resources to ports in order to support NES.
[0101] In some implementations, a mapping 505 associated with a configuration may include available ports 515 and other ports 520 across resources 510 (e.g., resource 510-a and resource 510-b) . Available ports 515 may be mapped to a second mapping 525-a associated with a sub-configuration of the configuration, as described with reference to FIG. 4. The available ports 515 in the mapping 525-a may maintain a respective mapping to the resources 510, as indicated in the configuration, although the indices of the available ports 515 may change. In some cases, the second mapping 525-a may include dimensions, N1 and N2, which may not be supported at a UE. That is, a network entity may not configure the UE to perform port indexing for a mapping 525-a of some dimensions. For example, if a first dimension, N1, is greater than a second dimension, N2, port indexing may not be supported. Supported dimensions may be indicated in a table, such as Table 1, configured by a network entity, or any combination thereof. In these cases, the port indexing method for the sub-configuration may be different from the port indexing method of the configuration or than indicated in the configuration.
[0102] For example, a configuration may be associated with mapping 505 for resources 510. The available ports 515 of mapping 525 may be mapped to mapping 525-a. Mapping 525-a may have a first dimension of two and a second dimension of three (e.g., (N1, N2) = (2, 3) ) , which may not be supported. For example, Table 1 may indicate support for a first dimension of three and a second dimension of two, but not a first dimension of two and a second dimension of three.
[0103] Table 1: Example of Supported Dimensions
[0104] For cases where a second dimension may be larger than a first dimension (e.g., N2>N1) , the dimensions may be swapped, such that the first dimension may be larger than the second dimension. For example, the dimensions of mapping 525-a may be switched, resulting in mapping 525-b associated with the sub-configuration (e.g., (N1, N2) = (3, 2) ) , which may be supported, as shown in Table 1.
[0105] [Rectified under Rule 91, 19.12.2024]In some cases, a configuration may be indexed according to a port indexing method (e.g., mapping method 1, mapping method 2) , as described with reference to FIGs. 3A and 3B. In some examples, the sub-configuration, as shown in mapping 525-a, may use the same port indexing method as the configuration (e.g., mapping method 1) . If the dimensions are swapped, as in mapping 525-b, the sub-configuration may use a different port indexing method as the configuration (e.g., mapping method 2) . The change in the port indexing method for the sub-configuration may be configured (e.g., via RRC signaling) or may be determined at the UE independently or based on a previous configuration.
[0106] FIG. 6 shows an example of a process flow 600 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The process flow 600 may implement, or be implemented by, aspects of the wireless communications systems 100 or 200 or port-to-resource mappings 300-500. For example, the wireless communications system 200 may include network entity 105-a and UE 115-a, which may be examples of corresponding devices as described herein, including with reference to FIGs. 1 and 2. The techniques described herein in the context of the process flow 600 may support methods support port indexing a sub-configuration based on the port indexing of a full configuration in order to map CSI-RS resources to ports in order to support NES.
[0107] At 405, the UE 115-b may receive, and the network entity 105-b may output, control signaling (e.g., first control signaling) that indicates a first configuration (e.g., configuration) . The first configuration may indicate a first mapping between a set of reference signal resources (e.g., CSI-RS resources) and a first set of ports at the network entity 105-b in accordance with a first ordering of a first set of indices. Additionally, or alternatively, the first configuration may indicate a second configuration (e.g., sub-configuration) . In some cases, the second mapping may include a bitmap, where the bitmap may indicate the subset of ports (e.g., available ports) of the first set of ports in accordance with the second configuration. In some cases, the subset of ports of the first set of ports may include available ports at the network entity 105-b in accordance with a NES procedure. In some cases, a reference signal resource of the one or more reference signal resources may be associated with a first polarization, a second polarization, and at least one port of the first set of ports, where the first mapping and the second mapping may be in accordance with the first polarization and the second polarization. In some cases, the first mapping, the second mapping, or both may be associated with a precoder (e.g., Equation 1) , where the precoder may indicate a mapping in accordance with the first polarization and the second polarization, where the mapping may include the first mapping, the second mapping, or both. In some cases, a quantity of indices in the first set of indices may be the same as a quantity of ports in the first set of ports, and a quantity of indices in the second set of indices may be the same as a quantity of ports in the subset of ports.
[0108] In some implementations, the second configuration may indicate a second mapping between one or more reference signal resources of the set of reference signal resources and a subset of ports of the first set of ports at the network entity in accordance with a second ordering of a second set of indices, where the second ordering of the second set of indices may be the same as the first ordering of the first set of indices. That is, the second configuration may indicate a same ordering of indices as the first configuration.
[0109] [Rectified under Rule 91, 19.12.2024]In other implementations, the second configuration may indicate a second mapping between one or more reference signal resources of the set of reference signal resources and a subset of ports of the first set of ports at the network entity 105-b in accordance with a second ordering of a second set of indices, where the second ordering of the second set of indices is based on the one or more reference signal resources such that the one or more reference signal resources are associated with one or more sets of consecutive indices, the second set of indices including the one or more sets of consecutive indices. In some cases, the second ordering of the second set of indices may not be the same as the first ordering of the first set of indices. For example, the second ordering of the second set of resources may be consecutive across a reference signal resource, as described further with reference to FIGs. 3A and 3B. In some cases, a quantity of sets of consecutive indices of the one or more sets of consecutive indices may be the same as a quantity of reference signal resources of the one or more reference signal resources.
[0110] In some cases, the second configuration may include a third mapping between the one or more reference signal resources of the set of reference signal resources and the subset of ports of the first set of ports at the network entity 105-b in accordance with a third ordering of the second set of indices, the third ordering of the second set of indices different than the first ordering of the first set of indices. For example, the sub-configuration may include dimensions that may not be supported in a wireless communications system. The UE 115-b may determine to use a different mapping (e.g., the third mapping) instead of the second mapping, as described further with reference to FIG. 5. In some examples, the UE 115-b may transmit a measurement report, as described at 620, based on a measurement procedure associated with the subset of ports of the first set of ports associated with the third mapping.
[0111] In some implementations, at 610, the UE 115-b may order one or more sets of indices based on the control signaling described at 605. For example, the UE 115-b may order the first set of indices according to a first ordering. In some cases, the first ordering may include ordering the first set of indices according to a first dimension (e.g., N1) , where the first set of ports are indexed with the first set of indices, where half of the first set of ports associated with a first polarization may be mapped to a reference signal resource of the one or more reference signal resources with a consecutive set of indices of the first plurality of indices (e.g., mapping method 1) . In other cases, the first ordering may include ordering the first set of indices according to a second dimension (e.g., N2, first dimension) , where the first set of ports are indexed with the first set of indices, where half of the first set of ports associated with a first polarization may be mapped to a reference signal resource of the one or more reference signal resources with multiple sets of consecutive indices of the first set of indices, where a quantity of the multiple sets of consecutive indices is equal to a size of a first dimension (e.g., N1, second dimension) , the first dimension different than the second dimension.
[0112] In some implementations, at 615, the UE 115-b may measure the one or more reference signal resources of the set of reference signal resources associated with the second mapping, where the measurement procedure may include measuring the one or more reference signal resources of the set of reference signal resources associated with the second mapping.
[0113] At 620, the UE 115-b may transmit, and the network entity 105-b may obtain, a measurement report based on a measurement procedure associated with the subsets of ports of the first set of ports associated with the second mapping, as described further at 605. In some examples, the UE 115-b may transmit the measurement report based on a measurement procedure associated with the subset of ports of the first set of ports associated with the third mapping, as described at 605.
[0114] FIG. 7 shows a block diagram 700 of a device 705 that supports port indexing for NES in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0115] The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to port indexing for NES) . Information may be passed on to other components of the device 705. The receiver 710 may utilize a single antenna or a set of multiple antennas.
[0116] The transmitter 715 may provide a means for transmitting signals generated by other components of the device 705.
